TE Connectivity 5-146288-9 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 5-146288-9 is a rectangular connector header designed for through-hole mounting applications. This 9-position, single-row connector operates at 0.100" (2.54mm) pitch and features male pins with kinked solder termination. The part is classified as obsolete, necessitating identification of active equivalent and substitute components for ongoing design and procurement requirements. Equivalent parts maintain identical electrical and mechanical specifications, while substitute parts provide functional alternatives with minor parameter variations.

Substitute Part Grouping Explanation

Substitution compatibility for the 5-146288-9 is determined by the following critical parameters: connector pitch (0.100" / 2.54mm), number of positions (9), contact type (male pin), mounting method (through-hole), and fastening mechanism (push-pull). All identified substitute parts maintain these core specifications.

The substitute parts are grouped into two categories:

Primary Equivalent (TE Connectivity): Part 5-146276-9 is the direct TE Connectivity equivalent, maintaining identical electrical and mechanical specifications while offering active product status and improved inventory availability.

Cross-Manufacturer Substitutes (Amphenol ICC / FCI): Parts 68004-109, 77311-122-09LF, 78229-209HTLF, 78511-209HLF, and 78511-409HLF are functionally compatible alternatives from Amphenol ICC. These parts share the critical parameters of 9-position configuration, 2.54mm pitch, male pin contact type, through-hole mounting, and push-pull fastening. Minor variations exist in contact length, insulation height, contact material composition, and operating temperature ranges, but these do not preclude functional substitution in applications designed for the original part.

Engineering Selection Recommendations

Primary Selection: TE Connectivity 5-146276-9

The 5-146276-9 is the recommended direct replacement for the obsolete 5-146288-9. Both parts are manufactured by TE Connectivity within the AMPMODU Mod II series and maintain identical electrical and mechanical specifications. The 5-146276-9 carries active product status with significantly higher inventory availability (4,807 units versus 838 units for the original part). Both parts are RoHS Compliant with identical operating temperature ranges (-65°C ~ 105°C), current ratings (3A), and material flammability certifications (UL94 V-0). The primary difference is termination style: the original part features kinked pin termination, while the equivalent uses standard solder termination. This distinction does not affect functional compatibility in applications designed for the original connector.

Secondary Selection: Amphenol ICC Cross-Manufacturer Substitutes

When TE Connectivity equivalents are unavailable, the following Amphenol ICC parts provide functional alternatives:

77311-122-09LF is the preferred Amphenol ICC substitute. This part maintains the critical 9-position, 2.54mm pitch configuration with male pin contacts and through-hole mounting. It carries active product status and RoHS Compliance. Operating temperature range extends to -65°C ~ 125°C, exceeding the original specification. Current rating matches at 3A per contact. Contact material differs (phosphor bronze versus copper alloy), but this substitution is functionally valid for standard applications.

78511-209HLF and 78511-409HLF are alternative Amphenol ICC options with identical mechanical configuration. Both support higher current ratings (5A) and extended operating temperature ranges (-65°C ~ 125°C). The 78511-209HLF features gold-plated mating contacts, while 78511-409HLF uses tin plating. Both carry RoHS Compliance and REACH Affected status.

68004-109 (BERGSTIK® II series) maintains core compatibility but carries RoHS Non-Compliant status. This part is suitable only for applications without RoHS requirements. Current rating is elevated to 5A.

78229-209HTLF offers press-fit and solder termination options, providing design flexibility. This part carries RoHS Compliance and active product status.

All Amphenol ICC substitutes maintain UL94 V-0 flammability ratings and MSL 1 moisture sensitivity levels, ensuring compliance with standard reliability requirements.

Frequently Asked Questions (FAQ)

Q: Can the 5-146276-9 directly replace the obsolete 5-146288-9 without design modification?

A: Yes. The 5-146276-9 is the direct TE Connectivity equivalent with identical pitch (2.54mm), position count (9), contact type (male pin), mounting method (through-hole), and fastening mechanism (push-pull). Both parts operate within the same temperature range (-65°C ~ 105°C) and current rating (3A). The only difference is termination style (kinked pin versus standard solder), which does not affect functional compatibility.

Q: What are the key compatibility criteria for substituting Amphenol ICC parts?

A: Functional substitution requires matching the following parameters: 9-position configuration, 0.100" (2.54mm) mating pitch, male pin contact type, through-hole mounting, and push-pull fastening. All listed Amphenol ICC parts meet these criteria. Secondary considerations include contact material (phosphor bronze versus copper alloy), contact finish (gold versus tin), and operating temperature range, which may vary but do not preclude substitution in standard applications.

Q: Are there RoHS compliance considerations when selecting substitutes?

A: Yes. The original 5-146288-9 and its direct equivalent 5-146276-9 are both RoHS Compliant. Most Amphenol ICC substitutes (77311-122-09LF, 78229-209HTLF, 78511-209HLF, 78511-409HLF) are also RoHS Compliant. The exception is 68004-109, which carries RoHS Non-Compliant status and is suitable only for applications without RoHS requirements.

Q: How do contact material differences affect substitution?

A: The original part uses copper alloy contacts, while Amphenol ICC substitutes use phosphor bronze. Both materials provide adequate electrical conductivity and mechanical durability for standard connector applications. Phosphor bronze offers superior spring characteristics and wear resistance, making it functionally equivalent or superior for most applications. Contact finish (gold or tin plating) provides corrosion protection and does not affect functional compatibility.

Q: What packaging options are available for substitute parts?

A: The 5-146276-9 (TE equivalent) is supplied in bulk packaging. Amphenol ICC substitutes are available in multiple packaging formats: 68004-109 (bag), 77311-122-09LF (bulk), 78229-209HTLF (tube), 78511-209HLF (bag), and 78511-409HLF (bag). Packaging selection does not affect electrical or mechanical performance and is determined by procurement and inventory management requirements.

Q: Can parts with higher current ratings (5A) substitute for the 3A-rated original?

A: Yes. Parts with higher current ratings (78511-209HLF, 78511-409HLF, 68004-109 at 5A) are functionally compatible with applications designed for 3A operation. The higher rating provides additional design margin and does not introduce incompatibility. However, applications requiring exactly 3A operation should prioritize parts with matching ratings (5-146276-9, 77311-122-09LF) to maintain design specification alignment.

Q: Are extended operating temperature ranges (up to 125°C) compatible with designs specified for -65°C ~ 105°C?

A: Yes. Parts with extended operating temperature ranges (-65°C ~ 125°C) are fully compatible with applications specified for -65°C ~ 105°C operation. The extended range provides additional design margin and does not introduce incompatibility. The connector will operate reliably within the original specification window.

Q: What is the significance of REACH Affected status on certain Amphenol ICC parts?

A: REACH Affected status indicates that the part contains substances subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulations. This status does not affect electrical or mechanical performance but may introduce regulatory compliance considerations for applications in European markets or subject to REACH requirements. Parts without REACH Affected designation (5-146276-9, 77311-122-09LF, 78229-209HTLF) are preferred for applications with strict regulatory requirements.
