Substitute Part Grouping Explanation

Substitution eligibility for the SR-5H-2.5A-APH is determined by strict equivalence across the following critical parameters:

• Current Rating: 2.5 A (exact match required)
• Voltage Rating (AC): 300 V (exact match required)
• Response Time: Slow Blow (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Can, Vertical (exact match required)
• Breaking Capacity @ Rated Voltage: 100 A (exact match required)
• Melting I²t: 45 (exact match required)
• Physical Dimensions: 0.335" Dia x 0.362" H / 8.50mm x 9.20mm (exact match required)
• DC Cold Resistance: 0.025 Ohms (exact match required)

The substitute part SR-5H-2.5A-AP meets all these criteria and is therefore classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both SR-5H-2.5A-APH and SR-5H-2.5A-AP are active products from Eaton - Electronics Division with identical electrical and mechanical specifications. The primary distinction between these parts relates to regulatory compliance status:

• SR-5H-2.5A-APH: RoHS non-compliant; Approval agencies include CCC, cURus, KC, PSE, SEMKO, VDE
• SR-5H-2.5A-AP: RoHS compliant; Approval agencies include CCC, cULus, KC-MARK, PSE, SEMKO, VDE; Operating temperature range specified as -40°C ~ 85°C

Selection between these equivalent parts should be based on the specific regulatory requirements of the end application and target market. Applications requiring RoHS compliance should specify SR-5H-2.5A-AP. Both parts are suitable for identical circuit protection applications where 2.5 A slow blow protection at 300 V AC/DC is required in through-hole radial board mount configurations.

Frequently Asked Questions (FAQ)

Q: Can SR-5H-2.5A-AP be used as a direct replacement for SR-5H-2.5A-APH?

A: Yes. Both parts are parametric equivalents with identical current rating, voltage rating, response time, mounting type, package format, breaking capacity, melting I²t, physical dimensions, and DC cold resistance. They are electrically and mechanically interchangeable.

Q: What is the primary difference between these two parts?

A: The main differences are RoHS compliance status and operating temperature specification. SR-5H-2.5A-AP is RoHS compliant with a specified operating temperature range of -40°C ~ 85°C, while SR-5H-2.5A-APH is RoHS non-compliant with no specified operating temperature range. Approval agency certifications also differ slightly between the two parts.

Q: Are there any packaging differences between SR-5H-2.5A-APH and SR-5H-2.5A-AP?

A: No. Both parts are supplied in Tape & Box (TB) packaging format.

Q: Which part should be selected for new designs?

A: For new designs, SR-5H-2.5A-AP is recommended due to its RoHS compliance status and specified operating temperature range, unless the application specifically requires the non-compliant variant or has other documented constraints.

Q: Are these parts suitable for both AC and DC applications?

A: Yes. Both parts are rated for 300 V AC/DC operation with identical electrical characteristics across both voltage types.
