DF9B-41P-1V(69) Equivalent & Substitute Parts

Part Overview

The DF9B-41P-1V(69) is a 41-position rectangular connector header manufactured by Hirose Electric Co Ltd, designed for surface mount applications with center strip contacts and gold plating. This connector is classified as an active product with RoHS compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the connector series, allowing for component interchangeability in applications where specific contact finish or base product variants are acceptable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF9B-41P-1V(69) is determined by maintaining the following critical parameters: 41-position count, 0.039" (1.00mm) pitch, 2-row configuration, surface mount mounting type, header connector type with center strip contacts, 4.3mm mated stacking height, and 0.130" (3.30mm) height above board. The identified substitute parts DF9-41P-1V(32) and DF9B-41P-1V(32) maintain all these core electrical and mechanical specifications. The primary difference between the main part and substitutes is the contact finish material and thickness: the main part features gold plating at 8.00µin thickness, while substitutes use tin plating at 39.4µin thickness. Both contact finishes are acceptable for equivalent electrical performance in the DF9 series connector family. Base product number variations (DF9 versus DF9B) and contact finish designations (69 for gold versus 32 for tin) represent standard Hirose product line differentiation without affecting functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and comply with RoHS requirements, ensuring regulatory compliance for current applications. The DF9B-41P-1V(69) with gold contact finish is the primary specification. The substitute parts DF9-41P-1V(32) and DF9B-41P-1V(32) with tin contact finish provide functional equivalence while maintaining identical mechanical dimensions and electrical performance characteristics. Selection between gold and tin finishes depends on application-specific requirements for contact resistance, corrosion resistance, and environmental exposure. The DF9B-41P-1V(32) maintains the same base product number (DF9B) as the main part, differing only in contact finish designation. The DF9-41P-1V(32) uses the DF9 base product number variant. Both substitute options are available in higher inventory quantities, supporting supply chain flexibility.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the DF9B-41P-1V(69)?

A: Substitution is valid when the connector maintains 41 positions, 0.039" (1.00mm) pitch, 2-row configuration, surface mount mounting, header type with center strip contacts, and identical stacking heights (4.3mm mated, 0.130" above board). Contact finish material and thickness variations are acceptable substitution parameters within the DF9 series.

Q: What is the difference between the DF9-41P-1V(32) and DF9B-41P-1V(32) substitutes?

A: Both parts are tin-plated 41-position connectors with identical electrical and mechanical specifications. The primary difference is the base product number designation: DF9 versus DF9B. The DF9-41P-1V(32) includes board guide features, while the DF9B-41P-1V(32) does not. Both are functionally equivalent for the core connector application.

Q: Can I use tin-plated substitutes in place of the gold-plated main part?

A: Yes, the tin-plated DF9-41P-1V(32) and DF9B-41P-1V(32) are electrically and mechanically equivalent to the DF9B-41P-1V(69). Contact finish selection depends on application requirements for contact resistance and environmental conditions. Both finishes maintain RoHS compliance and unlimited moisture sensitivity rating.

Q: Are all three parts available in the same packaging format?

A: Yes, all three parts are supplied in Tape & Reel (TR) packaging, ensuring consistent handling and assembly compatibility.

Q: What is the significance of the contact finish thickness difference?

A: The main part features 8.00µin (0.203µm) gold plating, while substitutes feature 39.4µin (1.00µm) tin plating. Both thicknesses are within acceptable ranges for the DF9 connector series and do not affect mechanical fit or electrical performance in standard applications.
