Substitute Part Grouping Explanation

Substitution of the TE Connectivity 146274-1 is determined by strict equivalence across the following critical parameters:

Core Compatibility Parameters:

Connector type (Header, Breakaway)
Contact type (Male Pin)
Number of positions (1)
Number of rows (1)
Mounting type (Through Hole)
Termination method (Solder)
Fastening type (Push-Pull)
Contact length at mating interface (0.318" / 8.08mm)
Contact shape (Square)
Current rating (3A)
Material flammability rating (UL94 V-0)
Insulation color (Black)

Variable Parameters (Post Length Variants): Substitute parts are differentiated by contact post length, which determines overall connector height and board penetration depth. Post length variants range from 0.120" (3.05mm) to 0.520" (13.21mm), creating distinct part numbers within the PBC01 and PEC01 base product families.

Material and Finish Variations: Substitute parts utilize phosphor bronze contact material with either gold or tin mating surface finishes, compared to the original copper alloy with tin-lead finish. All substitutes employ polybutylene terephthalate (PBT) insulation material instead of liquid crystal polymer (LCP).

Compliance Differences: All substitute parts are RoHS3 compliant and REACH unaffected, contrasting with the original part's RoHS non-compliance and REACH-affected status. Operating temperature range extends to 125°C for all substitutes versus 105°C maximum for the original.

Engineering Selection Recommendations

Primary Substitutes for Direct Replacement:

The PBC01SFAN and PEC01SFAN parts provide the closest dimensional match to the original 146274-1, with post lengths of 0.120" (3.05mm) compared to the original 0.125" (3.18mm). These variants maintain compatibility with existing PCB through-hole patterns and mating connector interfaces.

Compliance Advantage:

All listed substitute parts achieve ROHS3 compliance and REACH unaffected status, addressing regulatory requirements that the obsolete original part does not satisfy. This compliance status is mandatory for new production applications and equipment destined for markets with RoHS directives.

Operating Temperature Consideration:

Substitute parts support extended operating temperature range to 125°C, providing 20°C additional thermal margin compared to the original specification of 105°C maximum. This enhanced thermal capability accommodates applications with elevated ambient or component-generated heat.

Contact Finish Selection:

PBC01 series parts feature gold mating surface finish, offering superior corrosion resistance and contact reliability in environments with moisture or corrosive atmospheres. PEC01 series parts employ tin mating finish, providing cost-effective equivalence with adequate performance for standard industrial applications.

Post Length Variants:

Selection among post length options (0.120" through 0.520") depends on specific PCB thickness and connector stack-up requirements. The 0.120" post length variants (PBC01SFAN, PEC01SFAN) accommodate standard PCB thicknesses of 0.062" to 0.093". Longer post variants accommodate thicker substrates or additional component clearance requirements.

Frequently Asked Questions (FAQ)

Q: Can PBC01SFAN directly replace 146274-1 in existing designs?

A: PBC01SFAN maintains electrical and mechanical compatibility with 146274-1 across all critical parameters: single position, male pin contact, through-hole mount, 3A current rating, and push-pull fastening. The 0.120" post length is functionally equivalent to the original 0.125" specification for standard PCB applications. Physical dimensions and mating interface geometry are compatible.

Q: What is the difference between PBC01 and PEC01 series substitutes?

A: Both series employ identical connector geometry, contact length, and electrical ratings. The primary distinction is mating surface finish: PBC01 parts feature gold plating (10.0µin thickness) on mating contacts, while PEC01 parts employ tin finish (100.0µin thickness). Gold finish provides enhanced corrosion resistance; tin finish offers cost optimization for standard applications.

Q: How do post length variants affect PCB compatibility?

A: Post length determines the depth of contact penetration into the mating connector and the overall height of the assembled connector. Selection must account for PCB thickness, component clearance above the board, and mating connector cavity depth. The 0.120" post length (SFAN variants) suits standard 0.062" to 0.093" PCB thickness. Longer variants (SFBN through SFEN) accommodate thicker substrates or applications requiring extended contact engagement.

Q: Are all substitute parts RoHS compliant?

A: All listed Sullins substitute parts are ROHS3 compliant and REACH unaffected. The original TE Connectivity 146274-1 is RoHS non-compliant and REACH affected. Substitution with any listed part satisfies RoHS directive requirements for new production and equipment destined for regulated markets.

Q: What is the temperature operating range difference?

A: The original 146274-1 operates from -65°C to 105°C. All substitute parts extend the upper temperature limit to 125°C, providing 20°C additional thermal margin. This enhanced capability accommodates applications with elevated ambient temperatures or higher component-generated heat without performance degradation.

Q: Do substitute parts maintain the same current rating?

A: All substitute parts maintain the 3A current rating specified for the original 146274-1. Electrical performance and current-carrying capacity are equivalent across all listed alternatives.

Q: What insulation material differences exist between original and substitutes?

A: The original 146274-1 employs liquid crystal polymer (LCP) insulation. All substitute parts utilize polybutylene terephthalate (PBT) insulation. Both materials achieve UL94 V-0 flammability rating and black color specification. PBT provides equivalent electrical and mechanical performance with improved cost efficiency.

Q: Can post length variants be mixed in the same application?

A: Post length selection must be consistent with PCB design and mating connector specifications. Mixing variants with different post lengths in the same assembly is not recommended unless the design explicitly accommodates variable connector heights. Verify PCB cavity depth and mating connector requirements before selecting post length variant.

Q: What is the inventory status of substitute parts?

A: PEC01SFAN maintains the highest inventory availability at 5,484 pieces. PBC01SFAN provides 11,073 pieces. Other variants range from 699 to 1,482 pieces in stock. Inventory levels support immediate procurement for production requirements.
