Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 1702473 qualifies as a direct substitute for the 1771020 based on the following critical parameters:

• Identical 2-position configuration with 0.098" (2.50mm) pitch
• Matching electrical specifications: 5 A current, 150 V voltage
• Compatible wire gauge range: 20-26 AWG
• Identical mounting orientation and surface mount technology
• Same wire termination method: screwless spring cage tension clamp
• Identical housing material: Liquid Crystal Polymer (LCP)
• Same color specification: Black
• Equivalent MSL rating: 1 (Unlimited)

The primary distinction is product status: 1702473 is active production, while 1771020 is obsolete. Both parts share the COMBICON PTSM series designation and maintain full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1702473 is the direct active equivalent for the obsolete 1771020. Both parts maintain identical electrical and mechanical specifications across all critical parameters. The 1702473 offers the advantage of active production status with higher current inventory availability (6219 pcs vs. 1059 pcs).

The 1702473 carries ROHS3 compliance, representing an updated regulatory certification compared to the original RoHS compliance of the 1771020. Both parts maintain REACH Unaffected status and EAR99 export classification.

For new designs or production transitions, the 1702473 is the appropriate selection. The Tape & Reel packaging of the 1702473 supports automated assembly processes typical in surface mount production environments.

Frequently Asked Questions (FAQ)

Q: Can the 1702473 directly replace the 1771020 in existing designs? A: Yes. Both parts share identical electrical ratings (5 A, 150 V), mechanical configuration (2-position, 2.50mm pitch), and wire termination method. No circuit or layout modifications are required.

Q: What is the difference between the two parts? A: The 1702473 is the active production equivalent of the obsolete 1771020. Differences include product status, packaging format (Tape & Reel vs. standard), and updated RoHS certification level (ROHS3 vs. RoHS). All functional and electrical parameters are identical.

Q: Are there any compatibility concerns with the Tape & Reel packaging? A: No. Tape & Reel packaging is standard for surface mount components and is compatible with automated pick-and-place assembly equipment. The component itself is identical to standard packaging variants.

Q: What wire gauges are compatible with both parts? A: Both the 1771020 and 1702473 accept wire gauges from 20 to 26 AWG, supporting a range of conductor sizes within the specified current and voltage ratings.

Q: Are both parts RoHS compliant? A: Yes. The 1771020 carries RoHS compliance, while the 1702473 carries the updated ROHS3 compliance. Both meet current regulatory requirements for restricted substances.
