HARTING 09231487921 DIN 41612 48-Position Backplane Connector Header
Part Overview
The HARTING 09231487921 is a 48-position DIN 41612 backplane connector header designed for through-hole PCB mounting in right-angle configuration. This connector features male pins with gold or gold-palladium contact finish and is rated for 2A current per contact. The part is currently active in production with 667 units available in inventory. Alternative equivalent parts may be required due to supply constraints, design standardization across platforms, or specific application requirements for connector form factors within the DIN 41612 standard.

Substitute Part Grouping Explanation
Substitution eligibility for the HARTING 09231487921 is determined by the following critical parameters:
- Connector Standard Compatibility: Both parts must conform to DIN 41612 standard specifications
- Position Count: 48-position configuration required
- Pitch Specification: 0.100" (2.54mm) pitch maintained
- Row Configuration: 3-row arrangement
- Mounting Method: Through-hole, right-angle orientation
- Contact Material: Gold or equivalent noble metal finish
- Temperature Rating: Minimum -55°C to 125°C operating range
- Compliance: ROHS3 compliance required
The substitute part TE Connectivity AMP 5650916-5 qualifies as an equivalent based on these parameters. While it operates under the Eurocard series designation (C/2 style), it maintains full compatibility with the core DIN 41612 standard requirements for 48-position, 3-row, right-angle through-hole connectors with gold contact finish and equivalent temperature ratings.

Engineering Selection Recommendations
Both the HARTING 09231487921 and TE Connectivity 5650916-5 are active production parts with ROHS3 compliance and UL94 V-0 flammability ratings. Selection between these parts should be based on:
- Supply Availability: HARTING 09231487921 has 667 units in stock; TE Connectivity 5650916-5 has 80,198 units available
- Design Standardization: If your platform standardizes on either HARTING or TE Connectivity connectors, maintain that manufacturer preference
- Mechanical Fit: Both parts feature identical pitch, row count, and right-angle mounting; physical PCB layout compatibility is maintained
- Electrical Performance: Both parts support equivalent operating temperature ranges and contact materials suitable for standard backplane applications
Frequently Asked Questions (FAQ)
Q: Can the TE Connectivity 5650916-5 directly replace the HARTING 09231487921 on existing PCBs?
A: Yes. Both connectors maintain identical pitch (0.100"), row configuration (3 rows), position count (48), and right-angle through-hole mounting. PCB footprints are compatible.
Q: What is the difference between DIN 41612 "2C" style and "C/2" style?
A: Both designations refer to 3-row, 48-position DIN 41612 configurations. The HARTING uses "2C" nomenclature while TE Connectivity uses "C/2" (Eurocard) nomenclature. These are functionally equivalent within the DIN 41612 standard.
Q: Are the contact finishes equivalent?
A: The HARTING part specifies gold or gold-palladium finish; the TE Connectivity part specifies gold finish. Both are noble metal finishes suitable for equivalent electrical performance and corrosion resistance.
Q: What is the current rating difference?
A: The HARTING 09231487921 is rated for 2A per contact. The TE Connectivity 5650916-5 does not specify a current rating in the provided data. Verify the TE Connectivity part's current rating against your application requirements before substitution.
Q: Are both parts RoHS compliant?
A: Yes. Both the HARTING 09231487921 and TE Connectivity 5650916-5 are ROHS3 compliant with UL94 V-0 flammability ratings.
Q: What is the moisture sensitivity level for these connectors?
A: Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
