RF Attenuator R413808115 Equivalent & Substitute Parts

Part Overview

The Radiall USA R413808115 is an RF attenuator module designed for 8dB attenuation across 0 Hz to 4 GHz frequency range with 50 Ohm impedance and 2W power handling capability. This SMA in-line module is classified as Active product status and is RoHS Compliant. Substitute parts are identified when equivalent electrical parameters and mechanical form factors are required due to inventory constraints, supply chain considerations, or specific application requirements within the defined parameter envelope.

Key Parameters

Parameter	Value
Attenuation Value	8dB
Frequency Range	0 Hz ~ 4 GHz
Power Rating	2W
Impedance	50 Ohms
Package / Case	SMA In-Line Module
Moisture Sensitivity Level	1 (Unlimited)

Substitute Part Grouping Explanation

Substitute parts for the R413808115 are qualified based on the following core electrical and mechanical parameters:

Attenuation Value: Must be 8dB
Power Rating: Must be 2W minimum
Impedance: Must be 50 Ohms
Package / Case: Must be SMA In-Line Module
Frequency Range: Must encompass or match the 0 Hz ~ 4 GHz operating band

All identified substitute parts meet these mandatory criteria. Frequency range extensions beyond 4 GHz do not disqualify a part from substitution, as operation within the 0 Hz ~ 4 GHz band remains valid. Packaging format (Bulk vs. Bag) represents a logistical variable and does not affect electrical equivalence.

Engineering Selection Recommendations

All five substitute parts satisfy the core electrical and mechanical requirements for direct substitution with the R413808115. Selection among these equivalents should be based on the following factors:

RoHS Compliance Alignment: The R413808115 is RoHS Compliant. Four substitute parts (ATS-1M1F-08DB2W, CGA-1040-08-SMA-02, P1AT-SAMF-6G2W-8, SF0929-6200-08) are ROHS3 Compliant, maintaining regulatory alignment. The M3933/25-74S is RoHS non-compliant and should be selected only when RoHS compliance is not a design requirement.

Frequency Range Coverage: The CGA-1040-08-SMA-02 matches the exact 0 Hz ~ 4 GHz frequency specification of the original part. The ATS-1M1F-08DB2W, P1AT-SAMF-6G2W-8, and SF0929-6200-08 extend to 6 GHz or 18 GHz respectively, providing broader bandwidth capability within the same form factor and power rating.

Inventory Availability: All parts are in stock. The M3933/25-74S offers the highest inventory level at 1040 pieces, while SF0929-6200-08 has the lowest at 659 pieces.

Packaging Format: The M3933/25-74S is supplied in Bag packaging, while all other substitutes are supplied in Bulk packaging. This distinction is logistical and does not affect electrical performance.

Frequently Asked Questions (FAQ)

Q: Can ATS-1M1F-08DB2W be used as a direct replacement for R413808115?

A: Yes. The ATS-1M1F-08DB2W meets all mandatory electrical parameters: 8dB attenuation, 2W power rating, 50 Ohm impedance, and SMA in-line module form factor. The extended frequency range to 6 GHz does not prevent operation within the 0 Hz ~ 4 GHz band. ROHS3 compliance maintains regulatory alignment with the original part.

Q: What is the difference between the frequency ranges listed for substitute parts?

A: Frequency range indicates the upper operational limit of the attenuator. Parts specified for 6 GHz or 18 GHz can operate at any frequency up to their rated maximum, including the 0 Hz ~ 4 GHz band required by the R413808115. Extended frequency range does not affect performance within the original specification envelope.

Q: Is M3933/25-74S suitable for applications requiring RoHS compliance?

A: No. The M3933/25-74S is RoHS non-compliant. If RoHS compliance is a design or regulatory requirement, select from ATS-1M1F-08DB2W, CGA-1040-08-SMA-02, P1AT-SAMF-6G2W-8, or SF0929-6200-08.

Q: Does packaging format (Bulk vs. Bag) affect electrical performance?

A: No. Packaging format is a logistical consideration only and does not affect electrical characteristics, impedance, attenuation, or power handling capability. The M3933/25-74S supplied in Bag format is electrically equivalent to parts supplied in Bulk format.

Q: Which substitute part most closely matches the original R413808115 specification?

A: The CGA-1040-08-SMA-02 matches the exact frequency range specification of 0 Hz ~ 4 GHz. All other substitutes extend the upper frequency limit while maintaining identical attenuation, power rating, impedance, and form factor.
