Substitute Part Grouping Explanation

Substitute parts for the MF-NSML200/6-2 are categorized based on the following substitution criteria:

Upgrade Substitute (Voltage Rating Change): MF-NSML200/12-2 maintains identical current ratings (2A hold, 4A trip), resistance characteristics, package dimensions, and thermal operating range. The voltage rating increases from 6V to 12V, permitting use in higher voltage applications while preserving all other electrical and mechanical specifications.

Similar Substitute (Manufacturer Alternative): PTSLR12066V200 from Eaton - Electronics Division matches the original 6V voltage rating, 2A hold current, 4A trip current, and 1206 package form factor. This part provides direct functional equivalence from an alternative manufacturer with identical compliance certifications (cURus, TUV, ROHS3).

Parameter Comparison

Engineering Selection Recommendations

MF-NSML200/12-2 (Upgrade Substitute): Select this part when circuit design permits operation at 12V maximum voltage. All electrical performance parameters, thermal characteristics, and regulatory compliance remain equivalent to the original specification. This part is suitable for direct substitution in applications where voltage headroom is available.

PTSLR12066V200 (Similar Substitute): Select this part for direct voltage and current rating equivalence from Eaton - Electronics Division. This component maintains identical 6V/2A specifications and 1206 package compatibility. Both parts carry equivalent regulatory approvals (cURus, TUV) and ROHS3 compliance status.

All substitute parts maintain Active product status and are available in Tape & Reel packaging with Moisture Sensitivity Level 2A (4 Weeks).

Frequently Asked Questions (FAQ)

Q: Can MF-NSML200/12-2 be used as a direct replacement for MF-NSML200/6-2?

A: MF-NSML200/12-2 is functionally compatible when the circuit design operates at or below 6V. The 12V rating provides additional voltage margin. All current ratings, resistance characteristics, package dimensions, and thermal operating ranges are identical. Substitution is valid provided the application voltage does not exceed 6V.

Q: What is the primary difference between MF-NSML200/6-2 and PTSLR12066V200?

A: Both parts share identical voltage (6V), current (2A hold, 4A trip), and package specifications (1206 Concave). The primary difference is manufacturer: Bourns Inc. versus Eaton - Electronics Division. Electrical performance and regulatory compliance are equivalent.

Q: Are all substitute parts available in the same package configuration?

A: Yes. MF-NSML200/6-2, MF-NSML200/12-2, and PTSLR12066V200 are all supplied in 1206 (3216 Metric) Concave surface mount packages with Tape & Reel packaging. PCB footprint and reflow soldering parameters remain consistent across all three parts.

Q: Do substitute parts maintain the same regulatory certifications?

A: Yes. All three parts carry cURus and TUV approvals, ROHS3 compliance, and identical Moisture Sensitivity Level 2A (4 Weeks) ratings. ECCN and HTSUS classifications are consistent across all substitutes.

Q: What is the time-to-trip specification difference between MF-NSML200/6-2 and PTSLR12066V200?

A: MF-NSML200/6-2 specifies 5 seconds time to trip, while PTSLR12066V200 specifies 500 milliseconds. This represents a significant difference in response time. Select based on circuit protection requirements and acceptable trip delay for the application.
