IPD1-04-S-R Equivalent & Substitute Parts

Part Overview

The IPD1-04-S-R is a 4-position rectangular connector receptacle housing manufactured by Samtec Inc. as part of the Mini Mate® IPD1 series. This connector operates at a 0.100" (2.54mm) pitch with crimp termination and latch lock fastening, designed for free hanging in-line mounting applications. The part is ROHS3 compliant and carries an MSL rating of 1 (Unlimited). With 878 units in current stock and active product status, this component remains available for new designs and production applications. Equivalent substitute parts are identified based on matching electrical and mechanical parameters: 4-position receptacle configuration, 2.54mm pitch, female socket contacts, crimp termination, and latch lock fastening.

Engineering Selection Recommendations

All identified substitute parts maintain active product status and ROHS3 compliance, ensuring regulatory alignment with current manufacturing standards. The IPD1-04-S represents the closest functional equivalent, sharing identical manufacturer lineage, series designation, and material composition with the main part. The Molex 0050579704 and TE Connectivity 1379029-5 alternatives provide cross-manufacturer options with equivalent electrical and mechanical performance. Selection between substitutes should account for housing color requirements, insulation material specifications for thermal or chemical environments, and operating temperature ranges where applicable. All parts carry MSL 1 rating, eliminating moisture sensitivity constraints in component handling and storage.

Frequently Asked Questions (FAQ)

Q: What makes IPD1-04-S a direct equivalent to IPD1-04-S-R? A: Both parts share identical electrical and mechanical specifications: 4-position receptacle, 2.54mm pitch, female socket contacts, crimp termination, and latch lock fastening. Both are manufactured by Samtec Inc. within the Mini Mate® IPD1 series and maintain ROHS3 compliance and MSL 1 rating.

Q: Can Molex 0050579704 be used as a substitute in all applications? A: The Molex 0050579704 matches all critical electrical and mechanical parameters. Differences include housing color (black vs. white), insulation material (polyester glass-filled vs. polyamide), and operating temperature range (-40°C to 105°C vs. unspecified). Verify compatibility with your specific thermal and environmental requirements.

Q: What is the difference between the TE Connectivity 1379029-5 and the main part? A: The TE Connectivity part maintains functional equivalence across all core parameters. Distinctions include housing color (gray), insulation material (PBT glass-filled), and operating temperature range (-40°C to 85°C). The lower temperature ceiling may be relevant for high-temperature applications.

Q: Are contacts included with these connector housings? A: No. All listed parts are connector housings only. Contacts must be sourced separately and are not included with the housing purchase.

Q: Do all substitutes carry the same compliance certifications? A: Yes. All identified substitutes are ROHS3 compliant and carry MSL 1 (Unlimited) ratings, meeting current regulatory requirements for electronics manufacturing.

Q: Can housing color differences affect electrical performance? A: No. Housing color is a cosmetic and identification feature only and does not impact electrical or mechanical performance. Selection should be based on application requirements and design specifications.
