Equivalent & Substitute Parts for Molex 0510892005

Part Overview

The Molex 0510892005 is a 20-position rectangular connector housing (receptacle) with 2.00mm pitch, designed for free-hanging in-line applications. This connector belongs to the Mi II 51089 series and features female socket contacts with crimp termination. The part is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement continuity. Substitute connectors must maintain electrical and mechanical compatibility through matching pitch, position count, contact type, and termination method.

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0510892005 is determined by strict alignment with the following electrical and mechanical parameters:

Connector Type & Contact Configuration: All substitutes must be receptacle housings with female socket contacts to maintain mating compatibility with existing plug assemblies.
Position Count & Pitch: The 20-position configuration at 0.079" (2.00mm) pitch is the primary compatibility criterion. All substitute parts maintain this specification.
Row Configuration: Two-row arrangement is preserved across all substitutes to ensure proper contact alignment and spacing.
Mounting & Termination: Free-hanging in-line mounting with crimp termination is maintained across all alternatives.
Moisture Sensitivity: All substitutes maintain MSL 1 rating, indicating no moisture sensitivity constraints.

The three qualified substitutes—Amphenol ICC 10073599-020LF, Hirose DF11-20DS-2C, and JST PADP-20V-1-S—meet these core requirements while offering active product status and improved availability compared to the obsolete original part.

Engineering Selection Recommendations

Amphenol ICC 10073599-020LF is suitable for applications requiring extended operating temperature range (-55°C to 125°C). This part offers active product status with moderate inventory availability and RoHS compliance. Note that REACH status is listed as affected, requiring compliance verification for regulated markets.

Hirose DF11-20DS-2C provides the highest inventory availability (500,100 pcs) and maintains ROHS3 and REACH unaffected status, aligning with the original part's compliance profile. Operating temperature range is -30°C to 85°C. This option is optimal for high-volume procurement and applications with standard temperature requirements.

JST PADP-20V-1-S delivers strong inventory availability (4,460 pcs) with ROHS3 compliance and REACH unaffected status. Operating temperature range is -25°C to 85°C. This part includes latch lock fastening, providing mechanical retention advantages in certain mounting scenarios.

All three substitutes maintain the critical electrical and mechanical parameters of the original Molex 0510892005, including 20-position configuration, 2.00mm pitch, female socket contacts, and crimp termination. Selection should be based on application-specific temperature requirements, compliance obligations, and fastening preferences.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 10073599-020LF be used as a direct replacement for the Molex 0510892005?

A: The Amphenol ICC part maintains electrical compatibility through matching pitch (2.00mm), position count (20), contact type (female socket), and termination method (crimp). However, row spacing differs (0.079" vs. 0.098"), which may affect mechanical fit in existing assemblies. Physical validation is required before deployment.

Q: What is the significance of row spacing differences between the original and substitute parts?

A: The Molex 0510892005 specifies 0.098" (2.50mm) row spacing, while all three substitutes specify 0.079" (2.00mm) row spacing. This difference affects the overall connector footprint and may impact PCB layout compatibility. Mechanical fit verification is necessary for applications with space constraints.

Q: Are all substitute parts RoHS compliant?

A: All three substitutes carry RoHS compliance certifications. The Amphenol ICC part is RoHS compliant; the Hirose and JST parts are ROHS3 compliant. For applications requiring ROHS3 specifically, the Hirose DF11-20DS-2C and JST PADP-20V-1-S are preferred.

Q: Which substitute offers the best availability?

A: The Hirose DF11-20DS-2C provides the highest inventory level at 500,100 pcs, followed by JST PADP-20V-1-S at 4,460 pcs and Amphenol ICC 10073599-020LF at 1,101 pcs.

Q: Do the substitutes include contacts?

A: All parts, including the original Molex 0510892005 and all three substitutes, are housings only. Contacts are not included and must be procured separately.

Q: What are the operating temperature differences among substitutes?

A: Amphenol ICC 10073599-020LF operates from -55°C to 125°C, providing the widest range. Hirose DF11-20DS-2C operates from -30°C to 85°C, and JST PADP-20V-1-S operates from -25°C to 85°C. Application temperature requirements should guide selection.

Q: What is the difference between latch lock and standard fastening?

A: The Amphenol ICC and JST parts include latch lock fastening, providing mechanical retention of the connector assembly. The Hirose part does not specify a fastening type. Latch lock fastening enhances assembly security in vibration-prone environments.
