HARTING 09023647921 DIN 41612 64-Position Backplane Connector Header — Equivalent & Substitute Parts

Part Overview

The HARTING 09023647921 is a 64-position DIN 41612 connector header designed for through-hole PCB mounting in right-angle configuration. This component serves as a male pin interface for backplane applications requiring dual-row connectivity at 0.100" (2.54mm) pitch. The part is active in production and ROHS3 compliant, with 708 units currently in stock. Equivalent substitute parts are necessary when primary inventory is unavailable or when specific contact finish or thermal performance requirements necessitate alternative sourcing from qualified manufacturers.

Substitute Part Grouping Explanation

Substitution eligibility for the HARTING 09023647921 is determined by strict equivalence across the following parameters:

• Connector Type & Configuration: Header with male pins, through-hole mounting, right-angle orientation
• Electrical Interface: 64 positions, 2 rows, 0.100" (2.54mm) pitch, Style B
• Termination Method: Solder attachment to PCB
• Compliance & Environmental: ROHS3 compliance, MSL 1 rating, REACH unaffected status
• Mechanical Compatibility: Through-hole PCB mounting footprint and right-angle form factor

Three Hirose Electric Co Ltd PCN10 series variants meet these substitution criteria. All three parts maintain identical position count, pitch, row configuration, mounting type, and compliance certifications. Differences exist only in contact finish specification and board lock feature availability, which do not affect core electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three Hirose PCN10 series variants are functionally equivalent to the HARTING 09023647921 for backplane connector applications requiring 64-position DIN 41612 headers with 2.54mm pitch and right-angle through-hole mounting.

PCN10-64P-2.54DS(72) and PCN10A-64P-2.54DS(72) are interchangeable with the HARTING part for applications where board lock features are not required. Both maintain ROHS3 compliance and unlimited MSL rating.

PCN10EA-64P-2.54DS(72) includes integrated board lock functionality, matching the feature set of the original HARTING component. This variant is the preferred substitute when mechanical retention via board lock is specified in the design.

All substitute parts carry active product status and are available in higher inventory quantities than the primary part. Selection between the three Hirose variants should be based on board lock requirement and packaging preference (tray versus bulk).

Frequently Asked Questions (FAQ)

Q: Are the Hirose PCN10 series connectors mechanically compatible with the HARTING 09023647921 footprint?

A: Yes. All three Hirose variants maintain identical 64-position, 2-row configuration with 0.100" (2.54mm) pitch and right-angle through-hole mounting geometry, ensuring direct PCB footprint compatibility.

Q: What is the difference between PCN10-64P-2.54DS(72), PCN10A-64P-2.54DS(72), and PCN10EA-64P-2.54DS(72)?

A: PCN10-64P and PCN10A-64P are functionally identical without board lock features. PCN10EA-64P includes board lock functionality equivalent to the HARTING original part. All three share identical electrical specifications, contact finish (gold plating at 8.00µin), operating temperature range (-55°C to 85°C), and current rating (2A per contact).

Q: Does the gold contact finish on Hirose parts affect compatibility with the HARTING connector?

A: No. Gold plating is a standard contact finish for DIN 41612 connectors and does not affect electrical or mechanical compatibility. The 8.00µin (0.203µm) thickness meets industry standards for connector reliability.

Q: Are all substitute parts ROHS3 compliant?

A: PCN10-64P-2.54DS(72) and PCN10A-64P-2.54DS(72) are ROHS3 compliant. PCN10EA-64P-2.54DS(72) is RoHS compliant. All three parts are REACH unaffected and suitable for regulated applications.

Q: What is the MSL rating for these connectors?

A: All parts, including the HARTING original and all three Hirose substitutes, carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.

Q: Which substitute should I select if board lock is required?

A: PCN10EA-64P-2.54DS(72) includes board lock features and is the direct functional equivalent for applications requiring mechanical retention.
