Amphenol ICC 68648-003 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68648-003 is a vertical rectangular connector header with 10 positions at 2.54mm pitch, designed for through-hole mounting with solder termination. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing production and maintenance applications. The BERGSTIK® series header features shrouded 4-wall construction with male pin contacts and push-pull fastening, suitable for board-to-cable/wire interconnections in standard industrial and commercial electronics.

Substitute Part Grouping Explanation

Substitution eligibility for the 68648-003 is determined by strict alignment with the following core parameters:

Connector type: Header
Contact type: Male pin
Pitch: 0.100" (2.54mm)
Position count: 10 positions in 2 rows
Row spacing: 0.100" (2.54mm)
Shrouding: Shrouded 4-wall construction
Mounting: Through-hole solder termination
Insulation material class: Polyester or thermoplastic with UL94 V-0 rating
MSL rating: 1 (Unlimited)

Five substitute parts meet these core electrical and mechanical criteria. Substitutes are grouped into two categories based on fastening mechanism and contact finish specifications:

Group A (Push-Pull Fastening): 68666-003LF from Amphenol ICC maintains the original push-pull fastening type with updated contact finish specifications and RoHS compliance.

Group B (Detent Lock Fastening): 103169-3, 5-103169-3, 5-87587-1, and 87474-1 from TE Connectivity AMP Connectors feature detent lock fastening, which differs from the original push-pull mechanism but maintains all other core mechanical and electrical parameters.

Engineering Selection Recommendations

For RoHS Compliant Applications:

Select 68666-003LF, 5-103169-3, 5-87587-1, or 87474-1. These parts carry active product status with current RoHS or ROHS3 compliance certifications. The 68666-003LF maintains Amphenol ICC manufacturing continuity with push-pull fastening. TE Connectivity alternatives (5-103169-3, 5-87587-1, 87474-1) provide ROHS3 compliance with detent lock fastening and specified operating temperature ranges.

For Legacy System Maintenance:

The 68648-003 is obsolete. Direct replacement with 68666-003LF preserves the push-pull fastening mechanism and Amphenol ICC sourcing. If fastening mechanism change is acceptable, TE Connectivity AMPMODU Mod II series (103169-3, 5-103169-3, 5-87587-1, 87474-1) offers active product status with detent lock fastening.

For Temperature-Specified Applications:

TE Connectivity parts (103169-3, 5-103169-3, 5-87587-1, 87474-1) specify operating temperature range of -65°C to 105°C. The 68648-003 and 68666-003LF do not provide operating temperature specifications.

For Contact Finish Considerations:

68666-003LF uses palladium-nickel mating finish. 103169-3, 5-103169-3, and 87474-1 use gold mating finish. 5-87587-1 uses tin mating finish. Original 68648-003 specifies gold or gold GXT™ finish.

For Mechanical Mounting:

87474-1 includes mounting flange feature. All other substitutes lack this specification.

Frequently Asked Questions (FAQ)

Q: Can 68666-003LF directly replace 68648-003 in existing designs?

A: Yes. Both parts share identical pitch (2.54mm), position count (10), row configuration (2 rows), shrouding (4-wall), mounting type (through-hole), and termination (solder). Both use push-pull fastening. The primary difference is RoHS compliance status and contact finish specification (palladium-nickel versus gold/GXT™).

Q: What is the key difference between Group A and Group B substitutes?

A: Group A (68666-003LF) maintains push-pull fastening identical to the original 68648-003. Group B (TE Connectivity parts) uses detent lock fastening instead. Detent lock provides positive engagement with audible/tactile feedback, while push-pull relies on friction-based retention. This is a functional difference requiring design review if the mating connector is already specified for push-pull engagement.

Q: Are TE Connectivity AMPMODU Mod II parts (103169-3, 5-103169-3, 5-87587-1, 87474-1) interchangeable with each other?

A: All four TE Connectivity parts share identical core specifications: 10 positions, 2.54mm pitch, 2-row configuration, detent lock fastening, through-hole solder termination, and UL94 V-0 rating. Differences exist in contact finish (gold versus tin), insulation material (thermoplastic versus polyamide/nylon), and post finish specifications. 5-103169-3 and 5-87587-1 carry ROHS3 compliance; 103169-3 is RoHS non-compliant. Selection depends on RoHS requirement and contact finish specification for your application.

Q: Does contact finish affect electrical performance?

A: Contact finish affects corrosion resistance and long-term reliability in specific environmental conditions. Gold finishes (103169-3, 5-103169-3, 87474-1) provide superior corrosion resistance. Palladium-nickel (68666-003LF) and tin (5-87587-1) finishes have different environmental performance profiles. Consult application requirements for humidity, temperature cycling, and chemical exposure.

Q: What is the significance of the "LF" suffix in 68666-003LF?

A: The "LF" designation indicates lead-free compliance, consistent with RoHS requirements. This reflects the transition from lead-containing solder finishes to lead-free alternatives.

Q: Can I use 87474-1 if my PCB design requires a mounting flange?

A: Yes. 87474-1 is the only substitute part that includes a mounting flange feature. If your design specifies or requires flange mounting, 87474-1 is the appropriate selection among the available substitutes.

Q: What inventory levels are available for these substitute parts?

A: 68666-003LF: 959 pcs; 103169-3: 2104 pcs; 5-103169-3: 5212 pcs; 5-87587-1: 651 pcs; 87474-1: 1528 pcs. Inventory levels support production requirements across all substitute options.
