Mounting Type: Through Hole (all substitutes use through-hole mounting)
Voltage Rating (AC): 250V (all substitutes rated for 250V AC)
Operating Temperature Range: -25°C to 120°C (all substitutes operate within this range)
Filter Type: Power Line (all substitutes serve power line filtering)
Package / Case: Vertical, 4 PC Pin (all substitutes use identical pin configuration)
RoHS Status: ROHS3 Compliant (all substitutes meet compliance requirement)

Secondary Variation Parameters:

Inductance @ 1 kHz: ranges from 2.8 mH to 7.1 mH
Current Rating (Max): ranges from 3A to 3.5A
DC Resistance (Max): ranges from 100 mOhm to 120 mOhm
Physical Dimensions: two size classes (26.00mm × 20.50mm or 31.00mm × 22.50mm or 37.00mm × 35.00mm)

Substitution is valid when the application requirements allow tolerance in inductance value, current capacity, and physical footprint while maintaining all primary matching criteria.

Engineering Selection Recommendations

For Direct Footprint Compatibility (31.00mm × 22.50mm):

The SS30V-300054 and SS30V-R350047 maintain identical physical dimensions to the SS30V-R300071. SS30V-300054 provides 5.4 mH inductance with 3A current rating and 120 mOhm DCR, suitable for applications requiring lower inductance than the main part. SS30V-R350047 offers 4.7 mH inductance with enhanced 3.5A current capacity and reduced 100 mOhm DCR, appropriate for circuits requiring higher current handling.

For Compact Footprint Applications (26.00mm × 20.50mm):

The SS26V-300028 and SS26V-R300038 provide space-constrained alternatives. SS26V-300028 delivers 2.8 mH inductance with 100 mOhm DCR at 3A rating. SS26V-R300038 offers 3.8 mH inductance with identical electrical ratings, suitable when moderate inductance values are acceptable within the smaller package envelope.

For Larger Footprint Applications (37.00mm × 35.00mm):

The SS35H-35047 accommodates applications with available board space. This part matches the 4.7 mH inductance and 3.5A current rating of SS30V-R350047 while providing a larger physical footprint with reduced height (30.00mm).

Compliance Verification:

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and identical operating temperature ranges (-25°C to 120°C). All parts carry EAR99 ECCN classification and 8504.31.4065 HTSUS code. All substitute parts are active products with bulk packaging availability.

Frequently Asked Questions (FAQ)

Q: Can SS30V-R300071 be replaced with SS26V-300028 in a power line filtering circuit?

A: Substitution is valid only if the application circuit tolerates the reduced inductance value (2.8 mH versus 7.1 mH). The SS26V-300028 maintains identical 2-line configuration, 250V AC rating, 3A current capacity, and -25°C to 120°C operating range. Physical dimensions are smaller (26.00mm × 20.50mm versus 31.00mm × 22.50mm), requiring PCB layout verification.

Q: What is the difference between SS30V-R350047 and SS35H-35047?

A: Both parts provide identical electrical specifications: 4.7 mH inductance, 3.5A current rating, and 100 mOhm DCR. The primary difference is physical footprint. SS30V-R350047 measures 31.00mm × 22.50mm × 33.00mm height, while SS35H-35047 measures 37.00mm × 35.00mm × 30.00mm height. Selection depends on available board space and mounting constraints.

Q: Are all substitute parts through-hole mounted with 4-pin vertical configuration?

A: Yes. All substitute parts listed maintain through-hole mounting with vertical 4-pin configuration, ensuring mechanical compatibility with existing PCB designs that accommodate the SS30V-R300071.

Q: Which substitute part offers the closest electrical match to SS30V-R300071?

A: SS30V-300054 provides the closest match with 5.4 mH inductance (versus 7.1 mH), identical 120 mOhm DCR, 3A current rating, and matching 31.00mm × 22.50mm footprint. This part represents a lower inductance alternative within the same physical package class.

Q: Do all substitute parts meet the same compliance requirements as SS30V-R300071?

A: Yes. All substitute parts are ROHS3 compliant, REACH unaffected, carry EAR99 ECCN classification, and operate within -25°C to 120°C temperature range. All parts are active products with bulk packaging.

Q: Can SS30V-R300071 be replaced with SS35H-35047 in space-constrained applications?

A: No. SS35H-35047 has a larger footprint (37.00mm × 35.00mm) compared to SS30V-R300071 (31.00mm × 22.50mm). This part is suitable only for applications with available board space. However, it provides enhanced 3.5A current capacity and reduced 100 mOhm DCR compared to the main part's 3A rating and 120 mOhm DCR.
