Molex 0850420074 DIN Connector Receptacle - Equivalent & Substitute Parts

Part Overview

The Molex 0850420074 is a 48-position DIN connector receptacle with female sockets, gold contact finish, and through-hole solder termination. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new design implementations. The connector features a 0.100" (2.54mm) pitch, 3-row configuration in C/2 style, and operates across the -55°C to 125°C temperature range with UL94 V-0 flammability rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0850420074 is determined by the following critical parameters:

• Connector Type: Receptacle, Female Sockets (mandatory match)
• Number of Positions: 48 (mandatory match)
• Pitch: 0.100" (2.54mm) (mandatory match)
• Number of Rows: 3 (mandatory match)
• Mounting Type: Through Hole (mandatory match)
• Termination: Solder (mandatory match)
• Material Flammability Rating: UL94 V-0 (mandatory match)
• RoHS Compliance: ROHS3 Compliant (mandatory match)

The substitute parts listed below meet these core electrical and mechanical requirements. Variations in contact finish, insulation material composition, and style designation (C/2 vs. 2C) are permissible within the DIN 41612 and Eurocard connector families, as these do not affect functional interchangeability in standard backplane applications.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are active products with current manufacturing support, addressing the obsolescence status of the Molex 0850420074. Selection among the substitutes should be based on the following criteria:

HARTING 09232486824 and 09232486825: These parts maintain full DIN 41612 compliance with all 48 positions loaded. Both are manufactured from thermoplastic, glass-filled insulation materials and carry ROHS3 compliance. Contact finish specifications are not provided for these variants. These parts represent the most direct functional equivalents.

HARTING 09234486824: This variant includes gold-palladium contact finish with mounting clips and specifies a 2A current rating. Operating temperature range (-55°C to 125°C) and material composition (PBT, glass-filled) are explicitly documented. This part is suitable for applications requiring enhanced contact durability and defined current specifications.

TE Connectivity 5650459-5: This Eurocard series connector maintains the C/2 style designation matching the original Molex part, with gold contact finish and 32 loaded positions. RoHS compliance is confirmed, though REACH status is vendor-undefined. This part provides the closest mechanical and electrical alignment to the original specification.

All substitute parts meet mandatory compliance requirements (UL94 V-0, RoHS) and maintain the critical electrical parameters (48 positions, 0.100" pitch, 3-row configuration, through-hole solder termination).

Frequently Asked Questions (FAQ)

Q: Can HARTING 09232486824 and 09232486825 be used interchangeably with the Molex 0850420074?

A: Both HARTING parts meet the core substitution criteria: 48-position receptacle, female sockets, 0.100" pitch, 3-row configuration, through-hole solder termination, UL94 V-0 rating, and ROHS3 compliance. The primary difference is that HARTING parts load all 48 positions, whereas the original Molex part loads 32 positions. This does not affect functional compatibility in standard backplane applications.

Q: What is the difference between the HARTING 09234486824 and the other HARTING substitutes?

A: The 09234486824 variant specifies gold-palladium contact finish, includes mounting clips, and documents a 2A current rating. The operating temperature range (-55°C to 125°C) matches the original part. This variant is recommended for applications requiring explicit current specifications or enhanced contact performance.

Q: Why does the TE Connectivity 5650459-5 show different position loading than the original Molex part?

A: The TE Connectivity part loads 32 positions, matching the original Molex 0850420074 specification. Both maintain the C/2 style designation. Position loading does not affect mechanical or electrical interchangeability in standard backplane connector applications.

Q: Are all substitute parts RoHS compliant?

A: Yes. HARTING 09232486824, 09232486825, and 09234486824 are ROHS3 compliant. TE Connectivity 5650459-5 is RoHS compliant. All parts meet regulatory requirements for lead-free manufacturing.

Q: Can the HARTING 09281326902 (header, male pins) be used as a substitute?

A: No. The 09281326902 is a header with male pins, not a receptacle with female sockets. Connector type is a mandatory matching parameter and cannot be substituted.
