Engineering Selection Recommendations

Primary Recommendation: FCE17B25SA6EB (Amphenol ICC)

The FCE17B25SA6EB is the direct active-production equivalent from the same manufacturer (Amphenol ICC). This part maintains identical electrical and mechanical specifications to the FCC17B25SA6EB with the following distinctions:

Product Status: Active (vs. Obsolete)
RoHS Status: Compliant (vs. Non-compliant)
Flange Feature: Housing/Shell M3 (vs. Board Side M3) — represents a mechanical mounting variation
Current Rating: 5A (identical)
Operating Temperature: -40°C ~ 85°C (identical)

Selection of FCE17B25SA6EB is appropriate for applications requiring RoHS compliance and ongoing manufacturer support.

Secondary Recommendation: HARTING 09663126601 or 09663127601

HARTING part numbers 09663126601 and 09663127601 are functionally compatible substitutes with the following characteristics:

Product Status: Active
RoHS Status: ROHS3 Compliant
Current Rating: 6.5A (higher than main part 5A rating)
Operating Temperature: -55°C ~ 125°C (wider range than main part -40°C ~ 85°C)
Flange Feature: Housing/Shell M3 (matches FCE17B25SA6EB configuration)
Backset Spacing: 0.409" (10.40mm) — differs from main part 0.318" (8.08mm)

These parts are suitable for applications requiring extended temperature operation and higher current capacity. The backset spacing difference requires PCB layout verification.

Alternative HARTING Options by Flange Configuration:

Unthreaded Flange: 09663126600, 09663127600
4-40 Threaded Flange: 09663126602, 09663127602
Board Lock Feature (M3): 09663526611, 09663526615
Board Lock Feature (4-40): 09663526616

Selection among HARTING variants depends on specific mounting requirements and flange thread specifications for the target application.

Frequently Asked Questions (FAQ)

Q1: Can FCC17B25SA6EB be directly replaced with FCE17B25SA6EB?

A: Yes. Both parts are manufactured by Amphenol ICC and share identical electrical specifications (5A current rating, 200V voltage rating, -40°C ~ 85°C operating temperature). The primary difference is flange configuration (Board Side M3 vs. Housing/Shell M3) and RoHS compliance status. PCB mounting hole patterns must be verified for compatibility.

Q2: What is the significance of the backset spacing difference between Amphenol and HARTING parts?

A: Backset spacing defines the distance from the connector mounting face to the contact plane. The FCC17B25SA6EB and FCE17B25SA6EB specify 0.318" (8.08mm), while HARTING parts specify 0.409" (10.40mm). This difference affects PCB layout and mating connector alignment. Substitution requires confirmation that the receiving connector accommodates the different backset spacing.

Q3: Are HARTING parts suitable for legacy FCC17B25SA6EB applications?

A: HARTING parts are functionally compatible for signal applications with the same 25-position, 2-row D-Sub configuration. However, the backset spacing difference (0.409" vs. 0.318") requires mechanical verification. HARTING parts offer advantages in extended temperature range (-55°C ~ 125°C) and higher current capacity (6.5A), making them suitable for demanding environments. RoHS3 compliance is an additional benefit for regulated applications.

Q4: What does the flange feature designation mean?

A: The flange feature specifies the mounting mechanism:

Board Side (M3): M3 threaded holes on the connector body for board-side mounting
Housing/Shell (M3): M3 threaded holes on the shell for external bracket mounting
Housing/Shell (Unthreaded): Unthreaded holes for pin-type fasteners
Housing/Shell (4-40): 4-40 threaded holes for external bracket mounting
Board Lock: Integrated locking mechanism for secure board-level retention

Selection depends on the target PCB design and mechanical assembly requirements.

Q5: Why is RoHS compliance important for substitution?

A: RoHS (Restriction of Hazardous Substances) compliance is a regulatory requirement in many markets. The FCC17B25SA6EB is RoHS non-compliant, while FCE17B25SA6EB and all HARTING substitutes are RoHS compliant. For new designs or applications subject to RoHS regulations, compliant parts must be selected. For legacy system repairs where RoHS compliance is not mandated, non-compliant parts remain acceptable.

Q6: What is the difference between contact materials (Phosphor Bronze vs. Copper Alloy)?

A: Both Phosphor Bronze (main part) and Copper Alloy (HARTING substitutes) are acceptable contact materials for signal-level D-Sub connectors. Phosphor Bronze offers superior spring properties and wear resistance, while Copper Alloy provides cost efficiency. For signal applications at the specified current ratings (5A to 6.5A), both materials deliver equivalent electrical performance.

Q7: Can parts with different current ratings be substituted?

A: Yes, with the condition that the substitute part has an equal or higher current rating. The FCC17B25SA6EB is rated at 5A. HARTING substitutes rated at 6.5A are acceptable because they exceed the original specification. Substitution with a lower-rated part is not acceptable.

Q8: What inventory considerations apply to these substitutes?

A: All listed substitutes maintain active inventory levels ranging from 734 to 1127 pieces. The FCC17B25SA6EB (945 pieces) remains available despite obsolete status. For new designs, FCE17B25SA6EB (739 pieces) or HARTING parts with higher inventory (09663127601 at 1127 pieces) are recommended to ensure supply continuity.
