Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following core parameters:

Connector Type & Position Count: All substitutes maintain 72-position receptacle or header configuration
Pitch & Row Spacing: All substitutes maintain 0.100" (2.54mm) mating pitch and 0.100" (2.54mm) row spacing
Mounting & Termination: All substitutes use through-hole solder termination
Contact Configuration: All substitutes maintain female socket contacts with square shape
Flammability & MSL: All substitutes maintain UL94 V-0 rating and MSL 1 classification

The substitute parts are grouped into two categories:

Category 1 - Direct Receptacle Equivalent:

66953-036LF (Amphenol ICC): Active status receptacle with identical connector type and position configuration

Category 2 - Header Connector Alternatives:

NPPC362LFBN-RC, PPPC362LFBN-RC, PPTC362LFBN-RC (Sullins Connector Solutions): Header connectors with matching position count, pitch, and mounting specifications. Header connectors interface with receptacle connectors in board-to-board applications.

Engineering Selection Recommendations

66953-036LF is the primary substitute for direct replacement. This Amphenol ICC receptacle connector maintains identical connector type, position count, and pitch specifications. The part carries active product status with RoHS compliance and extended operating temperature range (-65°C ~ 125°C), providing superior environmental performance compared to the obsolete 76314-136LF.

NPPC362LFBN-RC, PPPC362LFBN-RC, and PPTC362LFBN-RC are header connector alternatives from Sullins Connector Solutions. These parts are suitable for board-to-board applications where the mating receptacle connector is available. All three maintain active product status and ROHS3 compliance. Selection between these three depends on contact finish requirements:

NPPC362LFBN-RC and PPPC362LFBN-RC feature gold mating contact finish with gold post finish
PPTC362LFBN-RC features tin mating contact finish with tin post finish

All Sullins alternatives operate within -40°C ~ 105°C temperature range with 250V voltage rating and 3A current rating.

Frequently Asked Questions (FAQ)

Q: Can 66953-036LF directly replace 76314-136LF? A: Yes. Both are 72-position receptacle connectors with 0.100" (2.54mm) pitch, through-hole solder termination, and push-pull fastening. The 66953-036LF maintains active product status and is the recommended direct equivalent.

Q: What is the difference between receptacle and header connectors in this application? A: The 76314-136LF and 66953-036LF are receptacle connectors designed to accept mating header connectors. The Sullins alternatives (NPPC362LFBN-RC, PPPC362LFBN-RC, PPTC362LFBN-RC) are header connectors that mate with receptacles. In board-to-board applications, one board uses a receptacle and the mating board uses a header connector.

Q: What are the contact finish differences among the Sullins alternatives? A: NPPC362LFBN-RC and PPPC362LFBN-RC provide gold mating contact finish with gold post finish. PPTC362LFBN-RC provides tin mating contact finish with tin post finish. Contact finish selection depends on application requirements for corrosion resistance and electrical performance.

Q: Are all substitute parts RoHS compliant? A: Yes. The 66953-036LF is RoHS Compliant. The Sullins alternatives (NPPC362LFBN-RC, PPPC362LFBN-RC, PPTC362LFBN-RC) are ROHS3 Compliant.

Q: What are the operating temperature differences? A: The 66953-036LF operates from -65°C ~ 125°C. The Sullins header alternatives operate from -40°C ~ 105°C. Application requirements determine which temperature range is appropriate.

Q: What packaging formats are available? A: 66953-036LF is supplied in Tube packaging. NPPC362LFBN-RC, PPPC362LFBN-RC, and PPTC362LFBN-RC are supplied in Tray packaging.
