Molex 0850130385 DIN Connector Header - Equivalent & Substitute Parts

Part Overview

The Molex 0850130385 is a 48-position DIN connector header with male pins, gold contact finish, and through-hole mounting. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations. The connector operates across the industrial temperature range of -55°C to 125°C and features press-fit termination with UL94 V-0 flammability rating.

Substitute Part Grouping Explanation

Substitution for the Molex 0850130385 is determined by the following critical parameters: connector type (header vs. plug configuration), number of positions (48), pitch (0.100"/2.54mm), number of rows (3), style (R/2), mounting type (through hole), operating temperature range (-55°C to 125°C), and contact finish (gold).

The substitute parts are grouped into two categories:

Category 1: Direct Functional Equivalents (Backplane DIN Connectors) Parts 5650479-5, 650479-5, and 5650477-5 from TE Connectivity AMP Connectors series maintain identical mechanical and electrical specifications as the main part. These are plug connectors (mating counterparts) with matching 48-position, 3-row, 0.100" pitch configuration and gold contact finish. All operate within the same temperature range and feature UL94 V-0 flammability rating.

Category 2: Alternative Backplane Header Part 09283486902 from HARTING is a DIN connector header (same connector type as the main part) with matching pitch, row count, and style. However, this part features gold-palladium contact finish and solder termination rather than press-fit, and uses PBT glass-filled insulation.

Category 3: Non-Equivalent Part Part 09455511122 from HARTING is a modular jack connector (RJ45/8p8c) and does not meet the substitution criteria for a 48-position DIN header. This part is listed in the source data but is not functionally equivalent.

Engineering Selection Recommendations

For applications requiring a direct header replacement with identical form factor and termination method, the HARTING 09283486902 is the only active substitute that maintains the header connector type. This part is ROHS3 compliant and active in production, addressing the obsolescence of the Molex 0850130385. The transition from press-fit to solder termination requires PCB design modification.

For mating plug applications or system upgrades, the TE Connectivity parts (5650479-5, 650479-5, and 5650477-5) provide active alternatives with full parameter compatibility. TE 5650479-5 is recommended for new designs due to ROHS3 compliance and active product status. TE 650479-5 is available but carries RoHS non-compliance and REACH-affected status, limiting suitability for regulated applications. TE 5650477-5 offers RoHS compliance with active status.

All recommended substitutes maintain the critical electrical and mechanical parameters: 48 positions, 0.100" pitch, 3-row configuration, R/2 style, through-hole mounting, gold contact finish, and -55°C to 125°C operating range.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity plug connectors (5650479-5, 650479-5, 5650477-5) directly replace the Molex 0850130385 header?

A: No. The Molex part is a header connector (receptacle), while the TE parts are plug connectors (male pins). These are mating components designed to work together. The TE plugs mate with compatible headers. For a direct header replacement, use HARTING 09283486902.

Q: What is the difference between the three TE Connectivity substitute parts?

A: All three TE parts share identical mechanical specifications (48 positions, 0.100" pitch, 3 rows, R/2 style, through-hole, gold finish, -55°C to 125°C). The differences are: 5650479-5 is ROHS3 compliant with active status; 650479-5 is RoHS non-compliant and REACH-affected; 5650477-5 is RoHS compliant. For new designs, 5650479-5 is preferred.

Q: Why does HARTING 09283486902 show a different style (2R vs. R/2)?

A: The style designation indicates the connector configuration. While both are 3-row DIN headers with 0.100" pitch, the 2R style differs from the R/2 style in mechanical layout. This difference may affect PCB footprint compatibility and mating connector selection.

Q: Is the HARTING 09283486902 suitable for applications requiring press-fit termination?

A: No. HARTING 09283486902 uses solder termination, while the Molex 0850130385 uses press-fit termination. PCB design changes are required to accommodate solder termination pads and assembly process modifications.

Q: Can HARTING 09455511122 (RJ45 modular jack) be used as a substitute?

A: No. The HARTING 09455511122 is an 8-position modular connector (RJ45/Ethernet), fundamentally different from the 48-position DIN header. It does not meet the electrical or mechanical requirements for substitution.

Q: What compliance considerations apply to these substitutes?

A: For regulated applications, TE 5650479-5 and HARTING 09283486902 are ROHS3 compliant and recommended. TE 650479-5 is RoHS non-compliant and REACH-affected, limiting use in regulated markets. All parts maintain UL94 V-0 flammability rating and operate within -55°C to 125°C.
