HARTING 09185107321 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The HARTING 09185107321 is a through-hole, right-angle rectangular connector header with 10 positions arranged in 2 rows at 0.100" (2.54mm) pitch. This shrouded, 4-wall design connector operates across -55°C to 125°C and is specified for board-to-cable/wire applications with solder termination and latch holder fastening. The part is active and ROHS3 compliant with unlimited moisture sensitivity rating.

Equivalent and substitute parts are necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility permits selection from qualified alternatives meeting identical electrical and mechanical specifications.

Engineering Selection Recommendations

All listed substitute parts maintain active product status and meet UL94 V-0 flammability requirements. Selection among qualified alternatives should prioritize the following factors:

ROHS3 Compliance Priority: Parts 0702471051, 2-1761605-3, D2510-5002-AR, HTST-105-04-G-D-RA, HTST-105-04-L-D-RA, and HTST-105-04-S-D-RA carry ROHS3 certification, matching the primary part specification. Parts 10056845-110LF, 75867-101LF, and 75867-301LF carry RoHS compliance without ROHS3 designation.

Operating Temperature Range: The HARTING 09185107321 operates -55°C to 125°C. Samtec HTST series (HTST-105-04-G-D-RA, HTST-105-04-L-D-RA, HTST-105-04-S-D-RA) and HARTING maintain this full range. TE Connectivity 2-1761605-3, 3M parts (30310-5002HB, D2510-5002-AR), and Molex 0702471051 operate to 105°C maximum, suitable for applications not requiring the full -55°C to 125°C envelope.

Inventory Availability: TE Connectivity 2-1761605-3 offers the highest stock level at 70,200 units. Molex 0702471051 provides 15,968 units. 3M D2510-5002-AR and 30310-5002HB offer 8,882 and 7,633 units respectively.

Contact Material and Finish: Phosphor bronze contacts (Molex, TE Connectivity, Amphenol ICC, Samtec) provide enhanced durability compared to copper alloy or brass alternatives. Gold-plated mating surfaces are standard across all options.

Frequently Asked Questions (FAQ)

Q: Can I substitute the HARTING 09185107321 with any of these parts directly?

A: Yes. All listed parts meet the core electrical and mechanical specifications: 10-position, 2-row, 2.54mm pitch, through-hole right-angle header with shrouded 4-wall design, solder termination, and UL94 V-0 rating. Physical footprint and mating interface are identical.

Q: What is the difference between ROHS3 and RoHS compliance?

A: ROHS3 represents compliance with the Restriction of Hazardous Substances Directive 2011/65/EU as amended. RoHS indicates compliance with the original directive. For new designs, ROHS3 compliance is the current standard. Parts marked RoHS without ROHS3 designation may still be acceptable depending on your supply chain requirements.

Q: Do the Samtec HTST series parts offer advantages over other substitutes?

A: Samtec HTST series (HTST-105-04-G-D-RA, HTST-105-04-L-D-RA, HTST-105-04-S-D-RA) feature liquid crystal polymer insulation and maintain the full -55°C to 125°C operating range matching the primary part. They support 3.4A per contact, exceeding most alternatives. The "G," "L," and "S" designations indicate post contact finish variations: gold, tin, and tin respectively.

Q: Which substitute offers the best inventory availability?

A: TE Connectivity 2-1761605-3 (AMP-Latch series) provides 70,200 units in stock, the highest availability among all options. Molex 0702471051 (C-Grid 70247) offers 15,968 units as a secondary option.

Q: Are there packaging differences I should consider?

A: Yes. The primary HARTING part ships in bulk packaging. Amphenol ICC Quickie™ series (10056845-110LF, 75867-101LF, 75867-301LF) and Samtec HTST series ship in tube packaging. 3M D2510-5002-AR ships in tray packaging. Molex 0702471051 and 3M 30310-5002HB ship in bulk. Verify packaging compatibility with your assembly process.

Q: What is the difference between the three Samtec HTST variants?

A: HTST-105-04-G-D-RA, HTST-105-04-L-D-RA, and HTST-105-04-S-D-RA differ only in post contact finish: gold (G), tin (L), and tin with thicker plating (S). All other specifications remain identical. Selection depends on soldering process requirements and post-plating durability needs.

Q: Can I use these parts interchangeably in existing designs?

A: Yes, provided your design does not depend on specific fastening type variations. The primary part uses latch holder fastening, while most substitutes employ push-pull fastening. Both secure the connector reliably; verify your mating connector compatibility before substitution.
