Substitute Part Grouping Explanation

The 172-E15-203R021 qualifies as a direct substitute for the 172-E15-201-021 based on the following critical parameters that determine functional and mechanical interchangeability:

Electrical Compatibility Parameters:

• Identical connector type (Receptacle, Female Sockets)
• Identical position count (15 positions)
• Identical row configuration (2 rows)
• Identical shell size and layout (2 DA, A)
• Identical current rating (5A)
• Identical operating temperature range (-50°C to 100°C)
• Identical contact material and finish (Brass with Gold Flash)

Mechanical Compatibility Parameters:

• Identical mounting type (Panel Mount)
• Identical termination method (Solder Cup)
• Identical shell material and finish (Steel, Nickel Plated)
• Identical dielectric material (PBT)
• Identical wire gauge compatibility (20-26 AWG)

Compliance Parameters:

• Both parts maintain ROHS3 compliance
• Both parts are manufactured by NorComp Inc. within the 172-E series

The primary difference between these parts is packaging format: the main part (172-E15-201-021) uses standard packaging, while the substitute (172-E15-203R021) is supplied in Tray packaging. This distinction affects only the receiving, storage, and handling procedures during manufacturing intake and does not impact electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

Both the 172-E15-201-021 and 172-E15-203R021 are active production parts from NorComp Inc. with full ROHS3 compliance certification. Selection between these parts should be based on the following engineering and operational criteria:

Primary Selection Criteria:

1. Packaging Requirements: Choose 172-E15-203R021 if your manufacturing process requires tray packaging for automated component handling or if your inventory management system is optimized for tray format. Choose 172-E15-201-021 if standard packaging aligns with your receiving and storage infrastructure.

2. Inventory Availability: The 172-E15-201-021 maintains higher current stock (1110 units) compared to 172-E15-203R021 (982 units). For immediate procurement needs, the main part number may offer shorter lead times.

3. Supply Chain Continuity: Both parts are active production items. Either part can serve as a long-term supply source without risk of obsolescence.

4. Cost Optimization: Packaging format differences may result in different unit pricing. Evaluate total cost of ownership including handling, storage, and processing labor when comparing alternatives.

Both parts deliver identical electrical performance, mechanical fit, and compliance characteristics for D-Sub 15-position panel mount applications requiring solder cup termination.

Frequently Asked Questions (FAQ)

Q: Can 172-E15-203R021 be used as a direct replacement for 172-E15-201-021 in existing designs?

A: Yes. The 172-E15-203R021 is electrically and mechanically identical to the 172-E15-201-021. All electrical parameters, mechanical dimensions, contact specifications, and compliance certifications are equivalent. The only difference is packaging format (Tray vs. Standard), which does not affect component performance or PCB assembly compatibility.

Q: What does the packaging difference mean for manufacturing?

A: Tray packaging (172-E15-203R021) is typically used for automated component placement systems and high-volume manufacturing environments. Standard packaging (172-E15-201-021) is suitable for manual assembly, lower-volume production, or environments where tray format is not required. Both formats contain the same connector with identical specifications.

Q: Are there any temperature or current rating differences between these parts?

A: No. Both parts have identical current ratings (5A) and identical operating temperature ranges (-50°C to 100°C). They can be used interchangeably in applications within these specifications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both 172-E15-201-021 and 172-E15-203R021 are ROHS3 compliant and manufactured to the same NorComp Inc. specifications within the 172-E series.

Q: Which part should I specify for a new design?

A: Either part is suitable for new designs. Specify based on your manufacturing process requirements: use 172-E15-203R021 if your assembly line requires tray packaging, or 172-E15-201-021 if standard packaging is preferred. Both will deliver identical performance and reliability.

Q: Are there any wire gauge or termination differences?

A: No. Both parts support identical wire gauge ranges (20-26 AWG) and use identical solder cup termination. They are fully compatible with the same PCB layouts and wiring practices.
