Substitute Part Grouping Explanation

Substitute parts for the FCC17B25PC21B are grouped into two categories based on parametric equivalence and functional compatibility:

Category 1: Direct Parametric Equivalents (Amphenol ICC FCE17 Series) These parts maintain identical electrical and mechanical specifications with the main part across all critical parameters: 25 position D-Sub plug configuration, right angle through-hole solder termination, DB/B shell size, 5A current rating, steel tin-plated shell, gold-plated phosphor bronze contacts, thermoplastic dielectric with glass fill, UL94 V-0 rating, and -40°C to 85°C operating temperature. The primary distinction is product status (active vs. obsolete) and RoHS compliance. These parts are: FCE17B25PC21B, FCE17B25PC20B, FCE17B25PC24B, FCE17B25PC25B, FCE17B25PC28B, FCE17B25PC29B, FCE17B25PC2DB, and FCE17B25PC2EB.

Category 2: Similar Functional Equivalents (HARTING Series) These parts provide functional D-Sub 25 position plug connectors with right angle solder termination and identical shell size/layout. Variations include higher current rating (6.5A vs. 5A), different backset spacing (0.409" vs. 0.590"), stamped contact form (vs. machined), copper alloy contacts (vs. phosphor bronze), and extended operating temperature range (-55°C to 125°C vs. -40°C to 85°C).

Engineering Selection Recommendations

For applications requiring direct replacement of the obsolete FCC17B25PC21B, the Amphenol ICC FCE17 series parts (FCE17B25PC21B, FCE17B25PC20B, FCE17B25PC24B, FCE17B25PC25B, FCE17B25PC28B, FCE17B25PC29B, FCE17B25PC2DB, FCE17B25PC2EB) are the primary substitutes. All FCE17 variants maintain identical mechanical and electrical specifications while offering active product status and RoHS compliance. These parts are functionally interchangeable with the original FCC17B25PC21B across all critical parameters including connector configuration, current and voltage ratings, operating temperature range, contact materials, and flammability certification.

The HARTING parts 09653226800 and 09653227800 provide functional D-Sub 25 position plug alternatives with identical shell size and right angle solder termination. These parts feature higher current capacity (6.5A), extended operating temperature range (-55°C to 125°C), and ROHS3 compliance. However, they differ in backset spacing (0.409" vs. 0.590"), contact material composition (copper alloy vs. phosphor bronze), and contact finish specification. These differences may affect mechanical fit and electrical performance in applications with specific spacing or contact resistance requirements.

For new designs or systems with RoHS compliance mandates, the Amphenol ICC FCE17 series is recommended. For applications requiring extended temperature operation or higher current capacity, the HARTING alternatives warrant evaluation against specific mechanical and electrical requirements.

Frequently Asked Questions (FAQ)

Q: Can FCE17B25PC21B directly replace FCC17B25PC21B in existing designs? A: Yes. The FCE17B25PC21B maintains identical electrical and mechanical specifications including 25 position configuration, 5A current rating, 200V voltage capability, -40°C to 85°C operating range, and right angle through-hole solder termination. The primary difference is active product status and RoHS compliance.

Q: What is the difference between the various FCE17B25PC models? A: All FCE17B25PC variants (PC20B, PC21B, PC24B, PC25B, PC28B, PC29B, PC2DB, PC2EB) share identical electrical and mechanical specifications. Differences are limited to internal design variations and packaging format (Box vs. standard). Selection among these variants depends on availability and packaging requirements.

Q: Are HARTING 09653226800 and 09653227800 fully compatible with FCC17B25PC21B? A: These HARTING parts provide functional D-Sub 25 position plug alternatives with identical shell size and right angle solder termination. However, they differ in backset spacing (0.409" vs. 0.590"), which affects PCB layout compatibility. The higher current rating (6.5A) and extended temperature range (-55°C to 125°C) may be beneficial for some applications but are not required for direct replacement of the original part.

Q: What does backset spacing mean and why does it matter? A: Backset spacing is the distance from the rear of the connector shell to the solder pin termination points. The FCC17B25PC21B and all FCE17 variants use 0.590" spacing, while HARTING parts use 0.409" spacing. This dimension is critical for PCB layout and component placement. Connectors with different backset spacing cannot be directly substituted without PCB redesign.

Q: Is RoHS compliance required for my application? A: RoHS compliance is mandated for products sold in the European Union and many other markets. The FCC17B25PC21B is RoHS non-compliant, while all FCE17 variants and HARTING parts are RoHS or ROHS3 compliant. For new designs or systems subject to RoHS regulations, compliant alternatives are necessary.

Q: What is the difference between machined and stamped contact forms? A: The FCC17B25PC21B and FCE17 variants use machined contacts, while HARTING parts use stamped contacts. Machined contacts typically provide more consistent contact resistance and durability. Stamped contacts are generally more cost-effective but may have slightly higher contact resistance variation.

Q: Can I use parts with different current ratings interchangeably? A: The FCC17B25PC21B and FCE17 variants are rated for 5A, while HARTING parts are rated for 6.5A. A higher-rated connector can be used in applications requiring lower current. However, using a lower-rated connector in a higher-current application is not acceptable. Verify that your application current requirements do not exceed the connector rating.
