FH21-15S-1DSA Equivalent & Substitute Parts

Part Overview

The FH21-15S-1DSA is a 15-position FFC/FPC vertical connector manufactured by Hirose Electric Co Ltd, designed for through-hole PCB mounting with 1.00mm pitch contacts. This connector features low insertion force (LIF) operation, phosphor bronze contacts with solder plating, and is rated for 50V and 0.5A applications across an operating temperature range of -30°C to 70°C.

The FH21-15S-1DSA is classified as obsolete. Equivalent and substitute parts are necessary to maintain design continuity and ensure component availability for new production runs and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the FH21-15S-1DSA is determined by strict alignment of the following critical parameters:

• Connector Configuration: 15-position FFC/FPC vertical connector
• Pitch: 0.039" (1.00mm) contact spacing
• Mounting Method: Through-hole PCB termination with kinked pins
• Electrical Ratings: Minimum 50V voltage rating and 0.5A current capacity
• Mechanical Compatibility: 0.30mm FFC/FPC thickness tolerance
• Environmental Tolerance: Operating temperature range of at least -20°C to 80°C

The two substitute parts listed—006232015006800+ (KYOCERA AVX) and 0528061510 (Molex)—meet these core substitution criteria. Both are active-status 15-position FPC connectors with 1.00mm pitch, through-hole mounting, kinked pin termination, and equivalent electrical ratings. Differences in contact material, housing material, and height above board do not prevent functional substitution within the specified electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

006232015006800+ (KYOCERA AVX): This substitute is active-status and ROHS3 compliant, addressing regulatory requirements that the obsolete FH21-15S-1DSA does not meet. The extended operating temperature range (-20°C to 85°C) provides additional thermal margin. The 0.30mm reduction in height above board (5.50mm vs. 5.80mm) is within typical PCB design tolerances for vertical connector applications. Copper alloy contacts with tin finish provide equivalent electrical performance for the specified 50V/0.5A ratings.

0528061510 (Molex): This substitute is active-status, ROHS3 compliant, and maintains the same contact material (phosphor bronze) and flammability rating (UL94 V-0) as the original part. The 0.40mm reduction in height above board (5.40mm vs. 5.80mm) is within acceptable mechanical tolerances. Tin contact finish and PPS housing material ensure compatibility with the electrical and environmental specifications. Mating cycle rating of 10 matches the original specification.

Both substitutes satisfy the core electrical, mechanical, and environmental parameters. Selection between them depends on specific design constraints regarding height above board, contact material preference, and regulatory compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can the 006232015006800+ and 0528061510 be used interchangeably with the FH21-15S-1DSA?

A: Both substitutes meet the critical substitution parameters: 15-position configuration, 1.00mm pitch, through-hole kinked pin termination, 50V/0.5A electrical ratings, and 0.30mm FPC thickness. The primary differences are height above board (5.50mm and 5.40mm respectively, versus 5.80mm for the original) and contact finish material. PCB layout must accommodate the reduced height. Both are functionally compatible within the specified electrical and mechanical parameters.

Q: What is the significance of the "2 Sided" versus "1 Sided" contact configuration?

A: The FH21-15S-1DSA features 2-sided contacts, while both substitutes feature 1-sided contacts. This refers to the contact arrangement within the connector housing. For 15-position connectors with 1.00mm pitch, 1-sided contact configuration is standard in active-production FPC connectors and provides equivalent electrical performance for the specified current and voltage ratings.

Q: Are there compliance differences between the original and substitute parts?

A: The FH21-15S-1DSA is RoHS non-compliant. Both substitutes (006232015006800+ and 0528061510) are ROHS3 compliant, meeting current regulatory requirements for new designs and production. The original part's UL94 V-0 flammability rating is maintained by the Molex substitute; the KYOCERA AVX substitute does not specify a flammability rating.

Q: How do the operating temperature ranges compare?

A: The FH21-15S-1DSA operates from -30°C to 70°C. The KYOCERA AVX substitute extends this to -20°C to 85°C, and the Molex substitute to -20°C to 80°C. Both substitutes provide wider high-temperature capability, though the lower temperature limit is reduced by 10°C. For applications requiring operation below -20°C, the original specification must be verified against actual system requirements.

Q: What packaging is available for the substitute parts?

A: Both substitutes are supplied in tray packaging, standard for production-volume FPC connector orders. The original FH21-15S-1DSA packaging is not specified in the available data.
