Substitute Part Grouping Explanation

Substitution eligibility for the PRG.M0.8GL.LC52Z is determined by the following critical parameters:

Connector Type & Position Count: Receptacle, female sockets, 8-position configuration
Termination Method: Solder cup termination for direct PCB or cable assembly integration
Fastening Mechanism: Push-pull detent lock for secure mating and demating
Contact Finish: Gold plating for reliable electrical contact and corrosion resistance
Shell Material: Polysulfone (PSU) for mechanical durability and thermal stability
Cable Opening Range: 0.157" ~ 0.205" (4.00mm ~ 5.20mm) for cable compatibility
Ingress Protection: IP50 rating for dust protection in industrial and automotive environments
Regulatory Compliance: ROHS3 compliance and REACH unaffected status

The substitute part K21M07-P08LFG0-527S from ODU meets these core substitution criteria while maintaining functional and mechanical compatibility.

Engineering Selection Recommendations

Both the PRG.M0.8GL.LC52Z and K21M07-P08LFG0-527S are active production parts with full ROHS3 compliance and REACH unaffected status, making them suitable for regulated applications in medical, automotive, and industrial sectors.

The PRG.M0.8GL.LC52Z supports a higher current rating of 5A and extended operating temperature range to 150°C, making it the preferred choice for high-power or high-temperature applications.

The K21M07-P08LFG0-527S operates at 3.85A with a maximum temperature of 120°C and includes integrated strain relief features. This part is suitable for applications within its specified electrical and thermal limits.

Selection between these parts should be based on application-specific current requirements and operating temperature constraints. Both parts maintain identical mechanical compatibility, fastening mechanisms, and regulatory compliance status.

Frequently Asked Questions (FAQ)

Q: Can K21M07-P08LFG0-527S be used as a direct replacement for PRG.M0.8GL.LC52Z?

A: Mechanical and electrical compatibility is confirmed for applications operating within the K21M07-P08LFG0-527S current rating (3.85A maximum) and temperature range (-50°C to 120°C). Applications requiring the full 5A rating or temperatures above 120°C require the PRG.M0.8GL.LC52Z.

Q: What are the key differences between these two parts?

A: The primary differences are current rating (5A vs. 3.85A) and maximum operating temperature (150°C vs. 120°C). The K21M07-P08LFG0-527S includes strain relief features. Both parts share identical connector type, position count, termination method, fastening mechanism, and contact finish specifications.

Q: Are both parts compliant with automotive and medical standards?

A: Both parts are ROHS3 compliant and REACH unaffected. Both are listed for automotive, industrial, medical, and testing equipment applications. Compliance with specific automotive or medical standards should be verified against application requirements.

Q: What is the cable opening compatibility between these parts?

A: Both parts support identical cable opening ranges of 0.157" ~ 0.205" (4.00mm ~ 5.20mm), ensuring cable assembly compatibility.

Q: Do these parts require any special handling or storage considerations?

A: Both parts have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control requirements during storage or handling.
