Key Parameters

Substitute Part Grouping Explanation

Substitution of the 172-E15-202R021 is determined by strict equivalence across the following critical parameters:

• Connector style, type, and position count (D-Sub, receptacle, 15-position)
• Shell size and layout (Size 2, DA/A configuration)
• Mounting method (panel mount)
• Termination type (solder cup)
• Contact material and finish specifications (brass with gold flash)
• Dielectric material (PBT)
• Wire gauge compatibility (20-26 AWG)
• Electrical ratings (5A current, operating temperature -50°C to 100°C)
• Compliance certifications (UL94 V-0, ROHS3)

The 172-E15-203R021 qualifies as a direct substitute based on identical values across all these parameters. The only difference is the shell material finish (nickel plated versus tin plated on the main part), which does not affect functional compatibility or electrical performance within the specified operating conditions.

Parameter Comparison

Engineering Selection Recommendations

The 172-E15-203R021 is the direct substitute for the obsolete 172-E15-202R021. Both parts maintain identical electrical and mechanical specifications, including current rating, operating temperature range, contact configuration, and termination method. The substitute part carries active product status, ensuring continued availability and manufacturing support.

Both parts satisfy ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for current procurement standards. The shell material finish difference (nickel plated versus tin plated) does not impact electrical performance or mechanical compatibility in standard operating environments.

Frequently Asked Questions (FAQ)

Q: Can the 172-E15-203R021 be used as a direct replacement for the 172-E15-202R021?

A: Yes. The parts are electrically and mechanically equivalent across all functional parameters including connector type, position count, shell size, mounting method, termination type, contact material, and electrical ratings.

Q: What is the difference between the tin plated and nickel plated shell finishes?

A: The shell material finish does not affect electrical performance or mechanical compatibility. Both finishes provide corrosion resistance appropriate for the operating temperature range of -50°C to 100°C.

Q: Are both parts RoHS compliant?

A: Yes. Both the 172-E15-202R021 and 172-E15-203R021 are ROHS3 compliant and REACH unaffected.

Q: Why is the main part listed as obsolete?

A: The 172-E15-202R021 has been discontinued by the manufacturer. The 172-E15-203R021 is the active equivalent part available for new procurement and system support.

Q: What wire gauges are compatible with these connectors?

A: Both connectors accept wire gauges from 20 to 26 AWG for solder cup termination.

Q: Are there any packaging differences between the two parts?

A: Both parts are supplied in tray packaging. The main part has 788 pieces in stock, while the substitute has 982 pieces in stock.
