Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCHURTER 7010.9973.53 is based on the following critical parameters:

Mandatory Matching Criteria:

• Current Rating: 15 A
• Fuse Type: Cartridge, Ceramic
• Mounting Type: Surface Mount
• Response Time: Slow Blow
• Package / Case: Cartridge, Non-Standard
• Series: MSB

The substitute part SCHURTER 7010.9973.57 satisfies all mandatory matching criteria. The primary distinction between the main part and its substitute is the product status transition from obsolete to active, coupled with the addition of specified voltage ratings (65 V AC / 65 V DC) and enhanced environmental specifications in the active variant.

Parameter Comparison

Engineering Selection Recommendations

The SCHURTER 7010.9973.57 is the direct active equivalent for the obsolete SCHURTER 7010.9973.53. Both components share identical core electrical characteristics: 15 A current rating, ceramic cartridge construction, slow blow response, and surface mount configuration within the MSB series.

The substitute part provides additional technical documentation through specified voltage ratings (65 V AC / 65 V DC), breaking capacity (150 A), and melting I²t (360), which were not declared for the obsolete variant. The substitute carries cURus approval certification and is ROHS3 compliant, supporting modern regulatory requirements. Operating temperature range (-55°C ~ 85°C) and dimensional specifications (2.00mm x 7.00mm) are provided for the active part.

Both parts share identical ECCN (EAR99) and HTSUS (8536.10.0040) classifications, confirming trade compliance alignment.

Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 7010.9973.57 directly replace the 7010.9973.53 in existing designs?

A: Yes. Both parts are identical in current rating (15 A), fuse type (ceramic cartridge), mounting method (surface mount), response time (slow blow), and package configuration (non-standard cartridge). The substitute is the active production equivalent.

Q: What is the primary reason for substitution?

A: The SCHURTER 7010.9973.53 is classified as obsolete. The SCHURTER 7010.9973.57 is the active equivalent part available for new procurement and ongoing supply.

Q: Are there voltage rating differences between the two parts?

A: The main part (7010.9973.53) does not specify voltage ratings in available documentation. The substitute (7010.9973.57) is rated for 65 V AC and 65 V DC. Designs operating within these voltage parameters are fully compatible.

Q: What packaging format is available for the substitute part?

A: The SCHURTER 7010.9973.57 is supplied in Tape & Reel (TR) format, standard for surface mount component distribution.

Q: Are there compliance or certification differences?

A: The substitute part carries cURus approval and is ROHS3 compliant. The main part does not specify these certifications. Both parts share identical ECCN and HTSUS classifications.

Q: What is the physical size of the substitute part?

A: The SCHURTER 7010.9973.57 measures 0.079" diameter by 0.276" length (2.00mm x 7.00mm), consistent with non-standard ceramic cartridge fuse dimensions.

Q: Is the substitute part suitable for the full operating temperature range of my application?

A: The substitute part operates across -55°C to 85°C. Verify this range meets your specific application requirements.
