SFPS-61T-250 Equivalent & Substitute Parts

Part Overview

The SFPS-61T-250 is a 0.250" (6.35mm) Quick Connect Female Crimp Connector manufactured by JST Sales America Inc., designed for 14-18 AWG wire applications. This non-insulated terminal operates in a right-angle, free-hanging configuration and is classified as an active product with full RoHS compliance. Substitute parts are identified when equivalent electrical and mechanical parameters align within the allowable specifications for this connector category, enabling direct replacement in applications where the primary part is unavailable or when inventory constraints require alternative sourcing.

Substitute Part Grouping Explanation

Substitution eligibility for the SFPS-61T-250 is determined by strict alignment of the following critical parameters:

Tab Width: 0.250" (6.35mm) — must match exactly for mechanical fit
Tab Thickness: 0.032" (0.81mm) — must match exactly for contact pressure and retention
Terminal Type: Angled - 90°, Flag — must match for mounting orientation and application fit
Gender: Female — must match for mating compatibility
Termination Method: Crimp — must match for assembly process compatibility
Contact Material and Finish: Brass with Tin — must match for electrical performance and corrosion resistance

Wire gauge range may extend beyond the primary specification (14-18 AWG) provided the substitute part's range encompasses the required gauge. Insulation diameter specifications must accommodate the intended wire sizes within the stated range.

Engineering Selection Recommendations

The TE Connectivity 42511-2 qualifies as a direct substitute for the SFPS-61T-250 based on matching critical mechanical and electrical parameters. Both parts maintain identical tab width, thickness, terminal type, gender, and contact specifications. The substitute part's wire gauge range (12-18 AWG) encompasses the primary part's specification (14-18 AWG), providing compatibility for all intended applications. Both parts carry equivalent environmental compliance certifications (RoHS and MSL 1), ensuring regulatory alignment. Tab length variance (0.307" versus 0.305") falls within acceptable manufacturing tolerances for this connector category. The substitute part is available in higher inventory volume (62,781 pcs versus 1,970 pcs), supporting supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the 42511-2 be used in place of the SFPS-61T-250 in existing designs?

A: Yes. The 42511-2 matches all critical mechanical and electrical parameters, including tab width, thickness, terminal type, and contact specifications. The substitute part's extended wire gauge range (12-18 AWG) accommodates all applications designed for the primary part.

Q: What is the significance of the wire gauge range difference?

A: The SFPS-61T-250 specifies 14-18 AWG, while the 42511-2 specifies 12-18 AWG. The substitute part's broader range encompasses the primary specification, ensuring compatibility for all intended wire sizes. No design modification is required.

Q: Are there packaging differences between these parts?

A: Yes. The SFPS-61T-250 is supplied in Tape & Reel (TR) packaging, while the 42511-2 is supplied in Cut Tape (CT) packaging. Packaging format does not affect electrical or mechanical performance; selection depends on assembly process requirements and inventory management practices.

Q: Do both parts meet the same compliance standards?

A: Both parts are RoHS compliant and carry MSL 1 (Unlimited) ratings. The SFPS-61T-250 is RoHS Compliant, and the 42511-2 is ROHS3 Compliant, both meeting current regulatory requirements for electronic component applications.

Q: What is the acceptable tolerance for tab length variation?

A: The tab length difference between these parts (0.307" versus 0.305", or 0.05mm) is within standard manufacturing tolerances for quick-connect terminals and does not affect mechanical fit or electrical performance in the intended application.
